Frequently Asked Questions 

FAQs about Windows 

What is double glazing?

Double-glazed windows are made of two panes of glass that are separated by a spacer bar. The space between the panes of glass are filled with Argon gas, which keeps the heat in and outdoor noise where it belongs - outside!

How long does double glazing last?

The technology behind double glazing is more advanced today than ever. 

If a double glazed window was produced today it will have a lifetime of

15-25+ years or more if the windows are fitted in a sheltered location and do not experience extreme weather. Here at Ullyett Glazing, we guarantee our PVCu windows for 10 years.

How does double glazing reduce noise?

Double glazing can reduce external sound wave energy. This helps reduce the volume of outdoor noise from entering your home.

Will new double glazing stop condensation?

Condensation is the result of the temperature difference from outside and inside your windows. On cold days the cooler side of the window will attract moisture from the air around the window. Condensation can appear on the outside and inside of a window. New windows should be able to solve the problem by reducing the inside and outside temperature difference on the panes of glass. Increasing air circulation can also help in the reduction of condensation. If you are experiencing extreme condensation we recommend you use a dehumidifier.

What are the best ways to clean PVCu window frames?

To avoid any discolouration or damage caused by over cleaning a regular wash with warm soapy water will keep your PVCu white window frames in great condition. We recommended you use a soft brush or cloth to take off any dust or loose dirt. If you can, hose down the windows with clean water followed by clean soapy water.

Do I need planning permission to change my front door?

Can you paint a PVCu door?
